At the start of the 2024 Republican primary campaign, Gov. Ron DeSantis of Florida was considered by many in his party to be the biggest threat to Donald Trump. He was seen as someone who could win over the voters who were tired of Trump’s antics, and also bring along the MAGA movement. But it didn’t work out that way. And as Mr. DeSantis has struggled, one main opponent, former Governor Nikki Haley of South Carolina, has seen her star — and her standing in the polls — rise.

Still, as the Trump alternatives crisscross Iowa and New Hampshire trying to appeal to voters, polling averages put the former president ahead by an average of 35 points.

Now, with just days to go until the Iowa caucuses, we ask: Did anti-Trump Republicans rally around the wrong candidates? And have they run out of time to fix it?
